A portable application can be run from a removable drive (USB flash drive, iPod, portable hard drive, etc) on any Windows computer without installation.
You will carry the program with settings on removable drive and don't modify settings on host computer.
On Vista and above turn off User Account Control (UAC) or run launcher as admin.

Hello @Bernat,as you may know, the mirror forum was taken down for about two weeks now. it seems like it is not in maintains, so probably you will need to contact the admin or the host author so to be able recover the info.That is a real disaster as it was the only place that centralize all portable developers work in a very good order with lot of mirrors, even for very old stuff.Thanks for all your works and reply.

Hi Bernat,Just want to inform you that JooSeng's forum is back now.Its a good opportunity to try making backup (offline explorer or teleport) of all your stuff there so you will be able to use those mirrors in case it will be removed again.
